Display open external ports from nftables firewall rules as sub-services
grouped by protocol. Only shows WAN incoming ports by filtering input chain
rules and excluding private network sources.
- Parse nftables ruleset for accept rules with dport in input chain
- Filter out internal network traffic (192.168.x, 10.x, 172.16.x, loopback)
- Extract single ports and port sets from rules
- Group and display as "TCP: 22, 80, 443" and "UDP: 53, 123"
- Update version to v0.1.247

permissions for ip netns exec commands.
- Change service name from transmission-vpn to openvpn-vpn-download
- Replace get_transmission_stats() with get_qbittorrent_stats()
- Use curl through VPN namespace to access qBittorrent API at localhost:8080
- Parse qBittorrent JSON response for state, dlspeed, upspeed
- Count active torrents (downloading, uploading, stalledDL, stalledUP)
- Update version to v0.1.246
Change docker images to use name field for all data instead of metrics,
matching the pattern used by torrent stats and VPN routes. Increase display
width for Status::Info sub-services from 18 to 50 characters to accommodate
longer informational text without truncation.
- Docker images now show: "image-name size: 994.0 MB" in name field
- Torrent stats show: "17 active, ↓ 2.5 MB/s, ↑ 1.2 MB/s" in name field
- Remove fixed-width padding for Info status sub-services
- Update version to v0.1.245
Implement aggregate torrent statistics display for transmission-vpn service
via Transmission RPC API. Shows active torrent count and total download/upload
speeds. Change VPN route label from "ip:" to "route:" for clarity.
- Add get_transmission_stats() method to query Transmission RPC

- Remove update_zmq_stats method
- Remove zmq_packets_received and zmq_last_packet_age fields
- Clean up display to only show essential information
- Handle 12th/13th Gen Intel format (e.g., "12th Gen Intel(R) Core(TM) i7-12700K")
- Extract full model including suffix (i7-12700K instead of truncated name)
- Simplify pattern matching logic
- Reduce fallback truncation to 15 chars
- Parse Intel models (i3/i5/i7/i9-XXXX) from full name
- Parse AMD Ryzen models (Ryzen X XXXX) from full name
- Display format: "i7-9700 (8 cores)" instead of full CPU name
- Reduces CPU section width significantly
Docker images now use Status::Info like VPN IP.
No "D" prefix, no status icon - just name and metrics.
All informational sub-services handled consistently.
Version: v0.1.239
Agent uses Status enum to control display:
- Status::Info: no icon, no status text (VPN IP)
- Other statuses: icon + text (containers, nginx sites)
Dashboard checks status, no hardcoded service_type exceptions.
Version: v0.1.237
Display VPN external IP as sub-service under openvpn-vpn-connection.
Query external IP through openvpn-namespace using curl ifconfig.me.
Version: v0.1.232
Collectors now clear their target vectors (tmpfs, drives, pools, services)
before populating to prevent duplicates when updating cached AgentData.
- Clear tmpfs list in memory collector
- Clear drives and pools in disk collector
- Clear services in systemd collector
- Bump version to v0.1.231
CRITICAL FIX: Collectors now update cached AgentData instead of
creating new empty data each cycle. This prevents the dashboard
from seeing flashing/disappearing data.
- Add cached_agent_data field to Agent struct
- Update cached data when collectors run
- Always broadcast the full cached data every 2s
- Only individual collectors respect their intervals
- Bump version to v0.1.230
Collectors now respect their configured intervals instead of running
every transmission cycle (2s). This prevents disk SMART checks from
running every 2 seconds, which was causing constant disk activity.
- Add TimedCollector wrapper with interval tracking
- Only collect from collectors whose interval has elapsed
- Disk collector now properly runs every 300s instead of every 2s
- Bump version to v0.1.229
Replace hardcoded terminal width thresholds with dynamic calculation
based on actual column requirements. Column visibility now adapts
correctly at 58, 52, 43, and 34 character widths instead of the
previous arbitrary 80, 60, 45 thresholds.
- Add width constants for each column (NAME=23, STATUS=10, etc)
- Calculate cumulative widths dynamically for each layout tier
- Ensure header and data formatting use consistent width values
- Fix service name truncation to respect calculated column width
Service panel now dynamically shows/hides columns based on terminal width:
- ≥80 chars: All columns (Name, Status, RAM, Uptime, Restarts)
- ≥60 chars: Hide Restarts only
- ≥45 chars: Hide Uptime and Restarts
- <45 chars: Minimal (Name and Status only)
Improves dashboard usability on smaller terminal sizes.
Root cause: sda's temperature exceeded threshold in the past, causing
smartctl to return exit code 32 (warning: "Attributes have been <= threshold
in the past"). The agent checked output.status.success() and rejected the
entire output as failed, even though the data (serial, temperature, health)
was perfectly valid.
Smartctl exit codes are bit flags for informational warnings:
- Exit 0: No warnings
- Exit 32 (bit 5): Attributes were at/below threshold in past
- Exit 64 (bit 6): Error log has entries
- etc.
The output data is valid regardless of these warning flags.
Solution: Parse output as long as it's not empty, ignore exit code.
Only return UNKNOWN if output is actually empty (command truly failed).
Result: Data_3 will now show "ZDZ4VE0B T: 31°C" instead of "? Data_3: sda"
Bump version to v0.1.225
Root cause: SMART data was collected TWICE:
1. Sequential collection during pool detection in get_drive_info_for_path()
using problematic tokio::task::block_in_place() nesting
2. Parallel collection in get_smart_data_for_drives() (v0.1.223)
The sequential collection happened FIRST during pool detection, causing
sda (Data_3) to timeout due to:
- Bad async nesting: block_in_place() wrapping block_on()
- Sequential execution causing runtime issues
- sda being third in sequence, runtime degraded by then
Solution: Remove SMART collection from get_drive_info_for_path().
Pool drive temperatures are populated later from the parallel SMART
collection which properly uses futures::join_all.
Benefits:
- Eliminates problematic async nesting
- All SMART queries happen once in parallel only
- sda/Data_3 should now show serial (ZDZ4VE0B) and temperature
Bump version to v0.1.224
Root cause: SMART data was collected sequentially, one drive at a time.
With 5 drives taking ~500ms each, total collection time was 2.5+ seconds.
When disk collector runs every 1 second, this caused overlapping
collections creating resource contention. The last drive (sda/Data_3)
would timeout due to the drive being accessed by the previous collection.
Solution: Query all drives in parallel using futures::join_all. Now all
drives get their SMART data collected simultaneously with independent
3-second timeouts, eliminating contention and reducing total collection
time from 2.5+ seconds to ~500ms (the slowest single drive).
Benefits:
- All drives complete in ~500ms instead of 2.5+ seconds
- No overlapping collections causing resource contention
- Each drive gets full 3-second timeout window
- sda/Data_3 should now show temperature and serial number
Bump version to v0.1.223
Root cause: run_command_with_timeout() was calling cmd.spawn() without
configuring stdout/stderr pipes. This caused command output to go to
journald instead of being captured by wait_with_output(). The disk
collector received empty output and failed silently.
Solution: Configure stdout(Stdio::piped()) and stderr(Stdio::piped())
before spawning commands. This ensures wait_with_output() can properly
capture command output.
Fixes: Empty Storage section, lsblk output appearing in journald
Bump version to v0.1.222
v0.1.220 broke disk collector by changing the import from
std::process::Command to tokio::process::Command, but lines 193 and
767 explicitly used std::process::Command::new() which silently failed.
Solution: Import both as aliases (TokioCommand/StdCommand) and use
appropriate type for each operation - async commands use TokioCommand
with run_command_with_timeout, sync commands use StdCommand with
system timeout wrapper.
Fixes: Empty Storage section after v0.1.220 deployment
Bump version to v0.1.221
- Changed disk collector to use tokio::process::Command instead of std::process::Command
- Updated run_command_with_timeout to properly kill processes on timeout
- Fixes issue where smartctl hangs on problematic drives (/dev/sda) freezing entire agent
- Timeout now force-kills hung processes using kill -9, preventing orphaned smartctl processes
This resolves the issue where Data_3 showed unknown status because smartctl was hanging
indefinitely trying to read from a problematic drive, blocking the entire collector.

The service_status_cache from discovery only has active_state with
all detailed metrics set to None. During collection, get_service_status()
was returning cached data instead of fetching fresh systemctl show data.
Now always fetch fresh data to populate memory_bytes, restart_count,
and uptime_seconds properly.
Shared:
- Add memory_bytes, restart_count, uptime_seconds to ServiceData
Agent:
- Add new fields to ServiceStatusInfo struct
- Fetch MemoryCurrent, NRestarts, ExecMainStartTimestamp from systemctl show
- Calculate uptime from start timestamp
- Parse and populate new fields in ServiceData
- Remove unused load_state and sub_state fields
Dashboard:
- Add memory_bytes, restart_count, uptime_seconds to ServiceInfo
- Update header: Service, Status, RAM, Uptime, ↻ (restarts)
- Format memory as MB/GB
- Format uptime as Xd Xh, Xh Xm, or Xm
- Show restart count with ! prefix if > 0 to indicate instability
All metrics obtained from single systemctl show call - zero overhead.
Changed header from 4 columns to 2 columns:
- Before: Service, Status, RAM, Disk
- After: Service, Status
Matches the removal of memory_mb and disk_gb fields.
Emoji rendering in terminals can be very slow, especially when rendered in the hot path (every frame for every docker image). The whale emoji 🐋 was causing significant rendering delays.
Temporary change to ASCII 'D' to test if emoji was the performance issue.
Docker images now display with distinctive 🐋 whale icon in blue (highlight color) instead of status icons. This provides clear visual identification that these are docker images while not implying operational status.
Changes:
- Rename docker images from 'image_node:18...' to 'I node:18...' for conciseness
- Change image status from 'active' to 'inactive' for neutral informational display
- Images now show with gray empty circle ○ instead of green filled circle ●
Docker images are static artifacts without meaningful operational status, so using inactive status provides neutral gray display that won't trigger alerts or affect service status aggregation.
Fixes random host disconnections caused by blocking operations preventing timely ZMQ packet transmission.
Changes:
- Add run_command_with_timeout() wrapper using tokio for async command execution
- Apply 10s timeout to smartctl (prevents 30+ second hangs on failing drives)
- Apply 5s timeout to du, lsblk, systemctl list commands
- Apply 3s timeout to systemctl show/is-active, df, ip commands
- Apply 2s timeout to hostname command
- Use system 'timeout' command for sync operations where async not needed
Critical fixes:
- smartctl: Failing drives could block for 30+ seconds per drive
- du: Large directories (Docker, PostgreSQL) could block 10-30+ seconds
- systemctl/docker: Commands could block indefinitely during system issues
With 1-second collection interval and 10-second heartbeat timeout, any blocking operation >10s causes false "host offline" alerts. These timeouts ensure collection completes quickly even during system degradation.
